IMPROVEMENT IN LAWN-MOWING M`ACHINES.

Specification forming part of Letters Patent o. 48,947, dated July 25, 1865.

To all 'whom it may concern;

Be itknown that we, JAMES A. HoUsE and HENRY A. HOUSE, both of Bridgeport, in the county of Fairfield and State of Connecticut, have invented a new and useful Improvement in Machines for Shearing Lawns, of which the following is a full, clear, and exaetdescription, reference being had to the accompanying drawings, which make part of this specification, and in which- Figure 1 represents a plan or top view of a machine for shearing lawns embracing our improvement, and Fig. 2 a vienr in elevation of one side of the same.

Our invention relates to that class of machines adapted to be Worked by haudpower for shearing lawns; and our improvement consists in the combination of a vibrating cutting apparatus with mechanism for actuating it, substantially in the manner hereinafter described.

A iinger-beam, A, curved in the are of a circle of large diameter, and made of a sled shape to run easily over the ground, is attached centrally to a frame composed in this instance of a single beam,B,projecting behind the lingerbeam. A scalloped cutter, C, curved to correspondWiththenger-beam, vbrates in guides c, secured to the beam. A vibrating bar or along the franIeB, to which it is pivoted near its center, so as to play horizontally on its fulcrnm d. The rear end of this arm is forked to em brace the edge of a cam-Wheel, E, mounted in suitable bearings in the frame, and rotated bya crank-arm, F. Theoperator pushes against a breast-piece, G, and propels the machine before him, (the finger-beam sliding on the ground,) and vibrates the cutters by turning the crank F.

By our invention we dispense with wheels, shoes, dividers, heavy frames, and complex gearing, and secure a strong, simple, compact, durable, and etlcient machine.

What we claim as .our invention, and desire to secure by Letters Patent A ot' the United States, is-

The combination of the finger-beam, frame, vibrating cutter, cam-gear, and breast-piece, arranged and operating substantially in the manner described, for the purpose set forth.

In testimony whereof We have hereunto subscribed our names.
